Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a foldable monitoring hospital bed. Background Art
[0002] In the field of medical care, foldable hospital beds are widely used in care scenarios with limited space due to their small occupied space and convenient storage. Traditional foldable hospital beds usually adopt a hinged bed board structure. One end of the bed board close to the wall is hinged to the lower part of the wall, and the other end far from the wall is obliquely pulled on the upper side of the wall by a rope to realize the unfolding and folding of the bed board. However, this structure has some pain points: when the bed board is folded into a vertical state, the rope that obliquely supports the outer end will be in a free and loose state because the upper and lower connection points are close. This loose state not only makes the overall appearance of the care space messy, but also may be hooked on surrounding equipment, clothing or personnel during handling and storage, causing tripping risks or equipment damage.
[0003] For example, in daily care, nursing staff need to pass by the foldable hospital bed frequently, and the loose rope may be wound around equipment such as nursing carts and infusion racks, increasing the complexity of operation. Some traditional designs solve the problem of scattering by manually bundling the rope, but the operation is cumbersome and cannot meet the need for rapid unfolding. Especially in the emergency scene, it may delay the treatment time. Therefore, a foldable monitoring hospital bed is proposed to solve the above problems.
[0004] The methods described in this section are not necessarily methods that have been previously conceived or adopted. Unless otherwise specified, any method described in this section should not be considered prior art solely because it is included in this section. Similarly, unless otherwise specified, the problems mentioned in this section should not be considered to have been recognized in any prior art. Summary of the Invention
[0005] The purpose of the present invention is to provide a foldable monitoring hospital bed to solve the problem that the ropes of traditional foldable hospital beds are freely scattered and easy to be hooked after the bed board is folded.
[0006] To achieve the above purpose, a technical solution adopted by the present invention is:
[0007] A foldable monitoring hospital bed, comprising a bed board and fixing components. There are two fixing components, and the two fixing components are symmetrically arranged on the left and right sides of the bed board. The fixing component includes a fixing seat, a rope and a rope storage component. The rear side of the end of the bed board in the length direction is hinged to the lower end of the fixing seat. The rope storage component is arranged at the upper end of the fixing seat. The lower end of the rope is connected to the front side of the end of the bed board in the length direction, and the upper end of the rope is connected to the rope storage component;
[0008] The drawstring storage assembly is used to store the drawstring when the bed board is folded and to release the drawstring when the bed board is unfolded. After the drawstring is completely released, the bed board is in a flattened state.
[0009] Further, the drawstring storage assembly includes a fixed cylinder, an elastic member, and a sliding member. One end of the fixed cylinder is fixedly connected to the fixed seat. The sliding member is slidably assembled inside the fixed cylinder. The upper end of the drawstring passes through the fixed seat and is fixedly connected to the sliding member. The elastic member is used to push the sliding member towards the side away from the fixed seat.
[0010] Further, the fixed cylinder extends transversely relative to the fixed seat, and the extending directions of the fixed seats of the two fixed assemblies are opposite to each other.
[0011] Further, the side of the bed board has two latches arranged at intervals along the length direction. When the bed board is folded, the fixed cylinder is located above the bed board, and the two latches will be respectively aligned with the two fixed cylinders, and the sliding member will partially protrude from the fixed cylinder for inserting into the corresponding latch.
[0012] Further, the sliding member includes a large-diameter sliding section and a small-diameter sliding section. The small-diameter sliding section is located on the side of the large-diameter sliding section away from the elastic member. A limiting member for restricting the large-diameter sliding section from sliding out is provided at one end of the fixed cylinder away from the fixed seat.
[0013] Further, the outside of the latch has an abutting guiding surface. During the folding process of the bed board, the large-diameter sliding section will abut against the limiting member. When abutting, the outer edge of the small-diameter sliding section can be pushed by the abutting guiding surface that flips upwards with the bed board, so that the sliding member slides towards the inside of the fixed cylinder.
[0014] Further, the elastic member is a helical spring. The helical spring is sleeved outside the drawstring and abuts against the fixed seat and the sliding member at both ends respectively.
[0015] Further, when the bed board is completely folded, the center of gravity of the bed board is located outside its hinge axis.
[0016] Further, the fixed seat is a profile with an L-shaped cross-section.
[0017] Further, the fixed seat has a plurality of through holes for assembling bolts.
[0018] The foldable monitoring hospital bed provided by the present invention significantly improves the practicability, safety, and operation convenience of medical equipment through innovative structural design. Its beneficial effects are as follows:
[0019] 1. The pull rope is automatically retracted and extended, solving the problem of traditional loose hook-up. Through the linkage of the fixed cylinder, sliding part and spiral spring in the pull rope storage component, the automatic storage and release of the pull rope with the folding / unfolding of the bed board is realized. When the bed board is unfolded, the spring is compressed to drive the release and tension of the pull rope to form a stable triangular support; when folding, the spring rebounds to drive the pull rope to be retracted into the fixed cylinder, avoiding the hidden danger that the pull rope is free and scattered and easy to be hooked after the traditional hospital bed is folded, and improving the cleanliness and use safety of the hospital bed.
[0020] 2. Automatic locking and convenient unlocking, improving operation efficiency. The mechanical linkage between the lock and the sliding part realizes automatic locking in the folded state: during the folding process of the bed board, the small-diameter sliding section is automatically clamped into the lock through the abutting guide surface, and the locking can be completed without manual operation. When unlocking, the double locks can be synchronously released by pulling the rope by two people or pushing the sliding part by one person. The operation is convenient and requires the simultaneous action of two locks, reducing the risk of accidental touch. In addition, the design of the center of gravity offset of the bed board enables it to automatically expand by gravity after unlocking, reducing the manual operation steps and meeting the requirements of emergency scenarios such as emergency departments.
[0021] 3. The structure is compact and stable, optimizing the space and installation experience. The fixed seat adopts an L-shaped profile structure, and the stability is ensured by installing through multi-hole bolts. Moreover, the layout of the fixed cylinders extending symmetrically horizontally is compact, reducing the space occupation and adapting to narrow medical environments. The limiting part restricts the sliding length of the large-diameter sliding section, avoiding excessive tension of the pull rope, and at the same time providing accurate positioning for the docking of the lock to ensure the reliability of locking. The overall structure is driven by mechanical linkage and elastic potential energy, without complex electronic control components, with low maintenance costs and strong durability, suitable for long-term and high-frequency use in medical scenarios.
[0022] 4. Function integration, improving nursing safety. The functions of pull rope storage, automatic locking and gravity-driven expansion are highly integrated, reducing the scattered components of traditional hospital beds and the operation complexity of nursing staff. For example, the locking structure in the folded state can prevent the accidental unfolding of the bed board, and the stable triangular support after unfolding ensures the load-bearing safety, especially suitable for the intensive care scenario in a narrow space. At the same time, avoiding the risk of pull rope hooking can reduce accidental injuries to patients, nursing staff and equipment, improving the safety of the medical environment and nursing efficiency.

Detailed implementation manners
[0033] The present invention will be further described below with reference to the accompanying drawings.
[0034] Referring to Figures 1 - 7 as shown, the foldable monitoring hospital bed of this embodiment includes a bed board 1 and a fixing assembly 2. There are two fixing assemblies 2, and the two fixing assemblies 2 are symmetrically arranged on the left and right sides of the bed board 1.
[0035] Specifically, the fixing assembly 2 includes a fixing base 21, a pulling rope 22 and a rope storage assembly 23. The rear side of the end of the bed board 1 in the length direction is hinged to the lower end of the fixing base 21, so that the bed board 1 can rotate around the hinge point to realize folding or unfolding. The fixing base 21 is used to be fixed to the wall. The fixing base 21 is a profile with an L-shaped cross-section, and this profile structure is stable and convenient for installation and fixation. At the same time, the fixing base 21 has a plurality of through holes for assembling bolts, which facilitates installing the fixing base at the required position through bolts, improving the convenience and reliability of the installation of the hospital bed. The rope storage assembly 23 is arranged at the upper end of the fixing base 21 and is used to automatically store or release the pulling rope 22; the lower end of the pulling rope 22 is connected to the front side of the end of the bed board 1 in the length direction, and the upper end of the pulling rope 22 is connected to the rope storage assembly 23;
[0036] The drawstring storage assembly 23 is used to store the drawstring 22 when the bed board 1 is folded and release the drawstring 22 when the bed board 1 is unfolded. After the drawstring 22 is completely released, the bed board 1 is in a flattened state. At this time, the drawstring 22 is in a taut state to maintain the horizontal support of the bed board 1.
[0037] In this embodiment, the drawstring storage assembly 23 includes a fixed cylinder 231, an elastic member 232, and a sliding member 233. One end of the fixed cylinder 231 is fixedly connected to the fixed seat 21 to form a fixed cavity for storing the drawstring 22. The sliding member 233 is slidably assembled in the fixed cylinder 231 and can move axially along the fixed cylinder 231. The upper end of the drawstring 22 passes through the fixed seat 21 and is fixedly connected to the sliding member 233. The drawstring 22 is retracted and released by the movement of the sliding member 233. The elastic member 232 is used to push the sliding member 233 away from the fixed seat 21 to provide power for the storage of the drawstring 22. The elastic member 232 is specifically a helical spring 2321, which is sleeved outside the drawstring 22 and abuts against the fixed seat 21 and the sliding member 233 at both ends, so as to push the sliding member 233 away from the fixed seat 21.
[0038] In the initial state, the bed board 1 is erected and leaned against the wall, and some locking measures can be used to keep the bed board 1 erected.
[0039] When the hospital bed is needed, first unlock the erected state of the bed board 1, and then hold the bed board 1 and pull it forward. The bed board 1 rotates forward around the hinge point at the lower end of the fixed seat 21 to unfold. During this process, the elastic member 232 in the drawstring storage assembly 23 is compressed because the sliding member 233 is pulled by the drawstring 22, driving the sliding member 233 to slide inwardly into the fixed cylinder 231, and the drawstring 22 is gradually released from the fixed cylinder 231. When the bed board 1 is completely flattened, the drawstring 22 is completely released and in a tensioned state, forming a stable triangular support structure together with the fixed seat 21 to ensure the load-bearing reliability of the bed board 1. In this state, the bed board 1 will remain flattened under its own weight and can be used for patients to lie on at this time.
[0040] When storing the hospital bed, turn the bed board 1 upward to fold it towards the fixed seat 21. As the bed board 1 rotates, the front end of the drawstring 22 moves upward with the bed board 1. At this time, the sliding member 233 gradually drives the drawstring 22 to be stored in the fixed cylinder 231 under the action of the elastic return of the elastic member 232. During the entire folding process, the drawstring 22 will be automatically stored in the fixed cylinder 231, so as to avoid the problem of loose hanging of traditional hospital beds. After storage, the structure of the hospital bed is compact and can save space occupancy. After folding, corresponding locking measures can be used to lock the posture of the bed board 1.
[0041] In this embodiment, the fixed cylinder 231 extends horizontally relative to the fixed seat 21, and the extending directions of the fixed seats 21 of the two fixed assemblies 2 are opposite. This layout makes the entire hospital bed structure compact, reduces space occupancy, and is also more beautiful.
[0042] In order to lock the folded bed board 1, the present embodiment also makes the following improvements. Specifically, two locking buttons 11 are provided on the side of the bed board 1 at intervals along the length direction. When the bed board 1 is folded, the fixed cylinder 231 is located above the bed board 1, and the two locking buttons 11 will be respectively aligned with the two fixed cylinders 231, and the sliding member 233 will partially extend out of the fixed cylinder 231 for inserting into the corresponding locking button 11.
[0043] Based on the above structure, in the initial state, the bed board 1 is erected and leaned against the wall. Under the pushing action of the elastic member 232, the sliding member 233 extends out of the fixed cylinder 231 and inserts into the corresponding locking button 11. The sliding member 233 on the other side will also insert into the corresponding locking button 11, and the posture of the bed board 1 is mechanically locked, making the folded state more stable. It is worth mentioning that the extending length of the sliding member 233 is determined by the length of the pull rope 22. The longer the length, the more it extends, and vice versa.
[0044] When unlocking is required, the two ends of the two pull ropes 22 extending out of the fixed cylinder 231 can be pulled to both sides respectively, so that the two sliding members 233 move away from each other and withdraw from the locking button 11, thus completing the unlocking operation. This unlocking operation generally requires two people. In addition, the operator can push the outer ends of the two sliding members 233 into the fixed cylinder 231 with the fingers of both hands respectively, and the unlocking operation can also be completed in this way. This unlocking operation can be completed by one person. Whether it is two-person unlocking or one-person unlocking, both locking buttons 11 need to be unlocked simultaneously to complete the unlocking operation, thus reducing the possibility of accidental touch and making it safer to use.
[0045] In this embodiment, when the bed board 1 is completely folded, the center of gravity of the bed board 1 is located outside its hinge axis. Thus, after the bed board 1 is unlocked, the bed board 1 can automatically flip forward by gravity, which can save the unfolding step and make it more convenient to use.
[0046] When locking is required, the sliding member 233 can be retracted into the fixed cylinder 231 by pulling the pull rope 22 in advance or pushing the sliding member 233 to make way for the folding of the bed board 1. After the bed board 1 is folded in place, release the pull rope 22 or the sliding member 233, and the sliding member 233 will reset under the action of the sliding member 233, thus completing the locking operation.
[0047] In this embodiment, the sliding member 233 includes a large-diameter sliding section 2331 and a small-diameter sliding section 2332. The small-diameter sliding section 2332 is located on the side of the large-diameter sliding section 2331 away from the elastic member 232. A limiting member 234 for restricting the large-diameter sliding section 2331 from sliding out is provided at one end of the fixed cylinder 231 away from the fixed seat 21. In this way, before the bed board 1 is completely folded and the lock 11 is aligned with the fixed cylinder 231, the limiting member 234 will abut against the large-diameter sliding section 2331. At this time, the length of the small-diameter sliding section 2332 extending out of the fixed cylinder 231 remains constant, and the extending length of the sliding member 233 remains fixed. In this way, the length of the sliding member 233 extending out of the fixed cylinder 231 can be restricted by a blocking form, rather than by the length of the pull rope 22. Such a setting can, on the one hand, prevent the pull rope 22 from being in a completely taut storage state, leaving a small amount of margin at the end of the fixed cylinder 231 so that the user can pick up the pull rope 22 for pulling operation; on the other hand, it can provide a stable position basis for the subsequent abutment of the small-diameter sliding section 2332 against the abutment guiding surface 111 on the lock 11.
[0048] In this embodiment, the outer side of the lock 11 has an abutment guiding surface 111. During the folding process of the bed board 1, the large-diameter sliding section 2331 will abut against the limiting member 234. When abutting, the outer edge of the small-diameter sliding section 2332 can be pushed by the abutment guiding surface 111 that flips upward with the bed board 1, so that the sliding member 233 slides inwardly into the fixed cylinder 231 against the elastic force of the elastic member 232, thereby making way for the flipping of the lock 11. When the lock 11 flips to be aligned with the fixed cylinder 231, the sliding member 233 will be reset and inserted into the lock 11 under the pushing action of the elastic member 232. In this way, automatic locking after flipping can be achieved, without pulling the pull rope 22 or pushing the sliding member 233, and the operation is more convenient.
[0049] In summary, the present invention discloses a foldable monitoring hospital bed. Through the collaborative design of multiple components, the foldable monitoring hospital bed realizes the optimization of structural compactness and functional reliability. The left and right symmetrical fixing components 2 are fixed to the wall through the fixing seats 21, and their lower ends are hinged to the bed board 1. The pull rope storage component 23 carried at the upper end becomes the core functional module. This component is linked by the sliding member 233 in the fixed cylinder 231 and the spiral spring 2321. When the bed board is unfolded, the spring compression is used to release the pull rope 22 to form a triangular support. When folding, the pull rope is automatically stored by the spring rebound, avoiding the traditional problem of loose hanging.
[0050] The cooperation between the buckle 11 and the sliding member 233 realizes the automatic locking in the folded state: when the bed board is folded, the small-diameter sliding section 2332 is automatically snapped into the buckle under the guidance of the abutting guiding surface 111, and the limiting member 234 restricts the large-diameter sliding section 2331 from sliding out, ensuring the locking accuracy. When unlocking, the double locks can be synchronously released by pulling the rope with two people or pushing the sliding member by one person, reducing the risk of accidental touch. The design of the offset center of gravity of the bed board enables it to automatically flip and unfold after unlocking. Combined with the transverse symmetric layout of the fixed cylinder, the space utilization rate and operation convenience are further improved. The whole set of structures is driven by mechanical linkage and elastic potential energy, which not only ensures the load-bearing stability, but also significantly optimizes the storage safety and use efficiency in the medical scenario.
[0051] The above embodiments only exemplarily illustrate the principles and effects of the present invention, rather than limiting the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
